2019 Press Releases

Morning Exercise Helps Keep Blood Flowing to the Brain All Day

Released April 11, 2019 - New research suggests that exercising early in the day protects brain blood flow from some of the negative effects from hours of sitting. The first-of-its-kind study is published ahead of print in the Journal of Applied Physiology. The paper was chosen as an APSselect article for April.

Released April 9, 2019 - A combination of over-the-counter antioxidants shows promise for mitigating some damaging effects of heart failure with preserved ejection fraction (HFpEF), a new study reports. The research, which will be presented today at the American Physiological Society’s (APS) annual meeting at Experimental Biology 2019 in Orlando, Fla., is the first to evaluate the efficacy of antioxidants to improve vascular function in patients with HFpEF.

Melatonin’s Heart Protective Effects Not Related to Its Antioxidant Properties

Released April 9, 2019 - Although melatonin does improve the outcomes of induced heart attacks in rats, those improvements are not the result of its antioxidant effect, new research finds. The study comparing antioxidant activity and heart protection will be presented today at the American Physiological Society (APS) annual meeting at Experimental Biology 2019 in Orlando, Fla.

Released April 7, 2019 - Device-guided breathing may improve physiological symptoms in people with severe posttraumatic stress disorder (PTSD), according to a new study. The findings will be presented today at the American Physiological Society’s (APS) annual meeting at Experimental Biology 2019 in Orlando, Fla.

Sunscreen Use Could Lead to Better Blood Vessel Health

Released April7, 2019 - A new study suggests that sunscreen protects the skin’s blood vessel function from harmful ultraviolet radiation (UVR) exposure by protecting dilation of the blood vessels. Perspiration on the skin may also provide protection to the skin’s blood vessels from sun damage. The findings will be presented today at the American Physiological Society’s (APS) annual meeting at Experimental Biology 2019 in Orlando, Fla.

Better Regulation of the Immune System May Minimize Preeclampsia Symptoms

Released March 5, 2019 - Boosting the body’s levels of interleukin-4 (IL-4)—an immune system protein that controls inflammation—may help manage the pregnancy complication preeclampsia, according to a new rodent study. The research, published in the American Journal of Physiology—Regulatory, Integrative and Comparative Physiology, was chosen as an APSselect article for March.

Hypertension-related Changes May Occur Earlier in Young Women with Family History

Released March 6, 2019 - New research suggests that young women with a family history of high blood pressure (hypertension) have decreased baroreflex function, which may increase their risk for hypertension later in life. The article, published ahead of print in the Journal of Neurophysiology (JNP), was chosen as an APSselect article for March.

Zinc Deficiency May Play a Role in High Blood Pressure

Released January 24, 2019 - Lower-than-normal zinc levels may contribute to high blood pressure (hypertension) by altering the way the kidneys handle sodium. The study is published ahead of print in the American Journal of Physiology—Renal Physiology.

Sex Differences in ‘Body Clock’ May Benefit Women’s Heart Health

Released January 10, 2019 - Research suggests that a gene that governs the body’s biological (circadian) clock acts differently in males versus females and may protect females from heart disease. The study is the first to analyze circadian blood pressure rhythms in female mice. The research, published ahead of print in the American Journal of Physiology—Regulatory, Integrative and Comparative Physiology, was chosen as an APSselect article for January.
